# Quickstart

Get up and running in minutes with the AI Game Developer app: download the app (or the gamedev CLI), sign in with your subscription, pick Unity, Unreal, or Godot, and the app installs and connects the right plugin for you — then start prompting your editor in plain language.

## 1. Get the Game Dev App

Download the AI Game Developer desktop app for Windows, macOS, or Linux (signed installers, auto-updates), or install the gamedev CLI — one app for Unity, Unreal Engine, and Godot. See the App guide (https://ai-game.dev/docs/app) for the full tour.

```bash
npm install -g @baizor/gamedev
gamedev
```

## 2. Sign in with your subscription

Open the app and choose Sign in. A browser window completes the secure OAuth device flow; your usage, history, and limits sync across the desktop app and the CLI. See the Authentication guide (https://ai-game.dev/docs/auth) for how sign-in works.

## 3. Pick your engine

Choose Unity, Unreal Engine, or Godot in the app (Brutal is coming soon). It installs the matching plugin, connects through ai-game.dev, and opens the editor for you. Prefer to install a plugin by hand or bring your own AI client? Each engine has an install guide (https://ai-game.dev/engines/unity, https://ai-game.dev/engines/unreal, https://ai-game.dev/engines/godot) with the advanced CLI setup.

## 4. Start building

Describe what you want in plain language and the agent drives your editor in real time — for example: "List everything in the active scene", "Create a cube at the origin and give it a physics body", or "Take a screenshot of the current view". Browse the full tools catalog (https://ai-game.dev/docs/tools) to see what else it can do.

## Common issues

- The sign-in browser window did not open — set a default browser and retry Sign in; corporate proxies may need outbound HTTPS to ai-game.dev allowed. See the Authentication guide (https://ai-game.dev/docs/auth).
- The engine plugin did not install — make sure the engine (Unity Hub, Unreal Engine, or Godot) is installed and point the app at a real project folder. You can also install directly from the per-engine install guide.
- The editor shows Disconnected after signing in — open the AI Game Developer window, choose Cloud, click Authorize, and wait for the status pill to read Ready. Review or revoke sessions on Connected devices (https://ai-game.dev/app/connected-devices).
- Bringing your own AI client — point it at the MCP endpoint and let it authorize over OAuth. The Authentication guide covers /mcp vs the pinned /mcp/p/<pin> URL, and https://ai-game.dev/mcp-endpoint-info has per-client config snippets.
